Retry +count is defined in the InfiniBand Spec 1.2 (12.7.38): +The total number of times that the sender wishes the receiver to retry tim- +eout, packet sequence, etc. errors before posting a completion error. + +Note that two mca parameters are involved here: +btl_openib_ib_retry_count - The number of times the sender will attempt to retry (defaulted to 7, the maximum value). +btl_openib_ib_timeout - The local ack timeout parameter (defaulted to 10). The actual timeout value used is calculated as: (4.096 micro-seconds * 2^btl_openib_ib_timeout). See InfiniBand Spec 1.2 (12.7.34) for more details. \ No newline at end of file
